Squid Girl

A young girl from the sea, calling herself Squid Girl, arrives on land with a mission to take over the world in retaliation for humanity's pollution of the ocean. But her plans quickly fall apart when she accidentally damages the beachside house she tries to use as her base. Forced to work off the debt under the watch of the Aizawa sisters who run the place, she struggles just to keep up with them-let alone conquer all of humankind.
